SPRAYING UNIT Filed Feb. 16 1928 .ZTI/E27 DF.' Adam `)Breuer Patented May 12, 1931 PATENT 'OFFICE ADAM 'A BREUE'R, or CHICAGO, ILLINOIS SPRAYING UNIT `v Application filed February 16, 1928. Serial No. 254,717.

This invention relates to spraying devices of the type in which the liquid isprojected in the form of a spray suspended in a current of air. l

`Usually sprays of this type are hand 0perated and consequently are intermittent in action and low in throwing power.

Further it has been customary to use metal liquid' containers so that the amount of' liquid therein -at any time cannot be seen.

One of the principal objectsof the present invention is to provide a simple, readily operated and cheap form of power driven spraying device.

A further object lof the invention is to provide a simplev form of spraying device adapted to the use of a glass liquid container. s

Other and further important objects' of this invention will be apparent from the disclosures in the accompanying drawings and the Vfollowing specification.

The invention (ina preferred form)I isV illustrated on the drawings and hereinafter more fully described.

On the drawings: Figure- 1 lis a side elevation of a sprayconstructed in accordance with my invention.

through the discharge end of the sprayer on the line II-II of Figure 3. t

Figure 3 is a section on the line III-III of Figure 2.

As shown on the drawings: The spraying device includelsan electrically driven fan 1 of the type commonly employed in vacuum cleaners having inlet and outlet orifices 2 and 3.respectively. A handle 4 is attached to-the motor casing and provided with a snap switch 17 for controlling the operation of the device.

The under side of the air discharge pipe y 5 of the spray is formed with a flat seat so that the cap of a glass Mason jar 7 may be clamped thereagainst. 'In this fiat seat a slot is cut centrally and longitudinally and a similar registering slot is cut in the cap 501. 6 and also in a felt or other washer 8 adapt- 'Figure 2 is a central vertical section elements for securing the same together, a

ed to `fit inside the cap and covered with tin or lead foil 9.

The cap and washer are clamped against the seat on the under side of the discharge pipe by a disc 10 held in placeby screws 55 11. On the upper side of lthis disc is a projecting portion 12 of substantially the same size as the slot and formed so that its upper surface is substantially flush with and a continuation of the inner wall of the pipe 5 except for a small lug 13. In the rear of the lug 13 is an air passage 14 passing through the disc 10 and its projection 12. The lug being disposed immediately in front of this passage actsas a dellector in aiding flow of air into thev jar 7 vthrough this passage.

The cap 6 has a threaded mar in adapted to engage the threaded top of t e glass jar 7. Extending from the rear bottom corner of the jar is a liquid supply tube 15 which passes through an aperture in the disc 12 and its projection 13. Conveniently the tube 15 is soldered or b razed to the disc 12. At its outer or discharge end the tube `15 is provided with a nozzle 16.

fniparting fromthe principles of this invention, and I therefore do not propose limiting the patent .granted .hereon otherwise than necessitated by the prior art.

I claim as my invention:

1. A spraying' apparatus including a blower, an air discharge pipe. leading from said blower, an open mouthed receptacle for a liquid, a cap removably secured to the underside of said discharge pipe, said receptacle and said cap having interfitting jet for liquid` disposed to discharge liquid into the stream of air passing through said discharge pipe inthe same direction as the ow of air in said pipe, a pipe extending from said jet to a point within the receptacle adjacent the bottom thereof, a disc cooperating with said discharge pipe for secur- ,uid in the receptacle end force it up the second mentioned pipe and out through said jet.

2. A device of thev kind set forth comprising a blower, an air discharge pipe leading therefrom having a slot in the underside, an o en-mouthed receptaclev having a threa ed lipfa correspondingly threaded cap, said cap having a slot adapted to register with the slot in said discharge pipe, a closure member for said slots having portions extending` lengthwise of said slots over the adjacent portlons of the cap,

vmeans for releasably clamping-said closure act on the liquid in the jar and member to the said discharge pipe and thereby holding/said cap in position, a pipe for liquid assing through and supported by said closure member, said member being" also provided with an air assage to allow the air pressure in the d1scharge pipe to orce it up the second pipe andout through said pipe.

3. A devlce as in claim 2 1n which the uppersurface of the closure member is substantiallyiush with the inner wall of the discharge pipe except for a projecting lip "adjacent the air passage in said member adapted'to aid in deiectln a portion of the air. passin through sai discharge pipe through sald passage. 4. spraying apparatus vvincluding' a blower, an air discharge pipe leading there-v from and having an aperture in the under- Supported in' Said. block, said liquid dig.V

charge pipe having its dischar e end within said air plpe and adjacent the ischarge end thereof, said liquid discharge pipe extending downwardly in an inclined direction below `said block, and a container removably associated with said clamped container cap, the lower end of said liquid discharge plpe terminating adjacent a lower rear portion of said container. 1

6. A sprayer unit including in combination, a blower, a discharge pipe therefor, said pipe having a seat on its under side, said seat having an o ening therethrough communicating with t e interior of sald pipe, a block removably associated with said seat and having a projecting part extending into said aperture, the up er surface of said projectin part being ius with the bottom of said ischarge plpe, a container cap clamped between said seat and said block, saidblock having an airpassage through it from top to bottom, said block having a deflector adjacent the upper end of said passage and behind the same with respect to the direction of air movement through said discharge pipe, a liquid discharge pipe supported-in said block, said pipe having its discharge end within said air discharge pipe and adjacent the discharge end thereof, said liquid discharge pipe extending downwardly below said block, and a container removably associated with said clamped container cap.
